COMIC torrent client question

im not sure this is the appropriate place to ask but i figured since so many of us get our anime through torrents, this would be the place.

i recently downloaded utorrent, (azureus and bitlord were messing up my internet so that if i started a torrent my net would crash but i would still be left with a green health and excellent connection display, anyone know of this)

how can i transfer the data from my previous torrents so that when i start the torrent in u torrent that i still have that level of completion? example, my flcl torrent is at 75%, when i save the torrent and open it with utorrent, it starts at 0. ive tried copy and pasting the data into the folder utorrent downloads into, but on the display it still starts with 0.

When I changed from BitLord to Utorrent i took the files in BitLord and changed the extension (taking off the .bc! at the end and if you can't see it go to the folder click tools > my folder > view tab > uncheck hide extensions for known file types)

Then I opened the torrent in Utorrent and when it asked where I wanted to save it I chose the folder that my anime from BitLord was downloading (In this case it was GITS so I opened up the GITS folder) and just start the torrent.

Before it starts downloading it should check and the percentage should go up little by little to the 75% that you downloaded previously, and start off from there.
